Description

Improved stainless steel bolt

Technical Field

The utility model relates to a stainless steel bolt technical field specifically discloses an improved generation stainless steel bolt.

Background

Stainless steel bolt means the material is the bolt of stainless steel, and current partial stainless steel bolt is at the in-process of installation and dismantlement, because the type of bolt head is more fixed, can only use single instrument to install and dismantle, and is more troublesome, and the bolt position can be connected with the connecting piece zonulae occludens after stainless steel bolt is installed for a long time simultaneously, is difficult to dismantle.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned defect or deficiency in the prior art, the application aims to provide an improved stainless steel bolt, which includes a bolt head and a bolt rod arranged at the bottom of the bolt head, wherein a dust cover is sleeved on the outer side of the bolt head, a screw located below the dust cover is sleeved on the middle part of the bolt head in a threaded manner, a first channel penetrating through the bolt rod to the middle part of the bolt head is arranged inside the bolt rod, and second channels communicated with the first channel are arranged on both sides of the bolt rod.

Preferably, the top of the dust cover is provided with a pull ring, and the inside of the dust cover is provided with a first limiting hole.

Preferably, the screw is internally provided with a second limiting hole which is distributed correspondingly with the first limiting hole.

Preferably, the shape of the bolt head is an annular hexagon, and the two sides of the bolt head are provided with straight grooves with the direction perpendicular to the second limiting hole.

Has the advantages that:

1. this improved generation stainless steel bolt sets up to annular hexagon and sets up the straight groove in the both sides of bolt head through the appearance with the bolt head and makes stainless steel bolt accessible multiple instrument install and dismantle, and is very convenient, utilizes the dust cover to protect the bolt head simultaneously, prevents that the dust gathering is inconvenient to be dismantled at the inboard of bolt head.

2. This improved generation stainless steel bolt is used through the cooperation at first passageway and second passageway for the inside injection lubricating oil of stainless steel bolt accessible dismantlement screw to first passageway after long-term the installation, and then lubricate shank of bolt and internal screw thread junction, so that dismantle stainless steel bolt.
